Method and system for delivering an interactive video

ABSTRACT

A method for delivering an interactive video is provided, including delivering a first video clip of the interactive video in a first loop, and upon receiving a first input during delivery of the first video clip, delivering a first exit sequence of the interactive video, the first exit sequence including a first exit video clip.

This application is the U.S. national phase of International Application No. PCT/GB2017/051797 filed Jun. 20, 2017 which designated the U.S. and claims priority to GB Patent Application No. 1610749.2 filed Jun. 20, 2016, the entire contents of each of which are hereby incorporated by reference.

FIELD

The present application is in the field of delivering video. More particularly, but not exclusively, the present application relates to interactive video.

BACKGROUND

Interactive video utilizes dynamic input to determine what video frames and/or video content is delivered. Interactive video can be used in entertainment, education, and gaming.

Previous methods of creating interactive content have used entirely computer-generated methods, including generating sprites, vectors, or 3d models, to produce video in response to real-time inputs. Computer-generated graphics can create precise event sequences in response to, for example, a user's input in a video game. Creating high-quality graphics that are realistic and engaging with computer-generated methods is processor-intensive, inefficient, and slow, however. For these reasons, higher quality interactive computer-generated graphics typically can only be accessed with computers that include advanced graphics processing units, such as desktop computers.

Previously, users have not been able to access higher quality interactive content using the lower performing hardware available on a smartphone or tablet computer, however, which offer more limited graphics processing units, and limited battery life.

In addition, creating high-quality interactive content including computer-generated graphics has entailed a tremendous cost and complexity for content creators. The expense and technical complexity required may bar those who would like to create high quality interactive video content from using computer-generated methods.

Rather than relying on computer-generated graphics rendered in real time to create interactive content, it is possible to use at least some previously generated video files. By providing previously generated video clips, such as live action video, this may avoid the need to dynamically render processor-intensive graphics in response to user inputs. The pre-generated videos can also use real actors and props, which can make interactive content appear more realistic than those using computer-generated graphics.

Creating interactive content based on previously generated video clips requires the dynamic integration of multiple pre-recorded clips in response to real-time user inputs. For example, a video game may, in response to user inputs, display a character sequentially walking in a first direction, sitting, then walking in a second direction. Each of the walking and sitting segments may be generated from a different pre-recorded video clip, for example a live action-based video clip.

Previously generated video-based products have been hindered by awkward pauses between video clips, and jarring transitions. For example, if two video clips delivered sequentially do not provide a careful transition in the position or orientation of a character, that character will appear to jerk or move unnaturally. Previous products have therefore not appeared responsive, or natural.

It is an object of the present applications to provide methods of delivering and generating interactive video that overcomes the disadvantages of the prior art, or at least provides a useful alternative.

FIG. 3 depicts system 300, in accordance with an embodiment. System 300 may facilitate the delivery of an interactive video. System 300 includes first client application 304. Sytem 300 may further include server application 302, second client application 306, and third client application 308.

Server application 302 may be configured to receive input from at least one of first client application 304, second client application 306, and third client application 308, and to deliver an interactive video.

First client application 304, second client application 306, and third client application 308 may further be configured to receive input and deliver an interactive video.

First and third client applications 304, and 308 may each communicate with server application 302.

In examples, second client application 306 may display an interactive video after receiving inputs from first client application 304.

In examples, server application 302, first client application 304, second client application 306, and third client application 308 may each operate on separate devices. For example, server application 302 may operate on server device 102; first client application 304 may operate on first client device 104; second client application 306 may operate on second client device 106; and third client application 308 may operate on third client device 108.

In further examples, however, the functions of any one of server application 302, first client application 304, second client application 306, and third client application 308 may be distributed across additional computing devices. For example, server application 302 may operate across a group of distributed servers.

FIG. 4 depicts method 400, an example embodiment that may execute within server application 302, first client application 304, second client application 306, or third client application 308. Method 400 may deliver an interactive video. An interactive video is a video including one or more video clips that may be delivered in response to one or more inputs.

For example, FIGS. 5A and 5B depict example interactive video 500. As may be seen in FIG. 5A, interactive video 500 includes a first video clip 504 and a first exit sequence 506. In further examples, interactive video 500 may further include an intro video clip 502, as will be further explained below.

Intro video clip 502, first video clip 504, and first exit sequence 506 are previously generated video clips. In examples, intro video clip 502, first video clip 504, and first exit sequence 506 may represent segments of a longer video, for example a previously generated video that captures multiple phases of action sequentially. In further examples, intro video clip 502, first video clip 504, and first exit sequence 506 may be produced separately.

Method 400 begins with step 402. In step 402, the first video clip 504 of the interactive video is delivered in a first loop. The first video clip is any video including one or more frames. In examples, the first video clip may include a video including a one or more characters or elements of interest at rest or otherwise in transition between input-based actions, waiting for a further input before taking the next action. For example, the first video clip may include a video game character breathing but other wise sitting still, or a stopped car emitting exhaust.

The first video clip 504 is delivered in a loop. A loop is a repeat playback of a video clip. A loop delivers one or more frames of a video clip sequentially in a frontwards direction, a backwards direction, or in a combination thereof.

In examples, first video clip 504 may include a series of key frames, key frames being intra frames, or complete images stored in a video file. In further examples, first video clip 504 may include both key frames and intermediate frames, intermediate frames being compressed delta frames, stored in a video file. In examples, method 400 may use one or more video codecs to convert intermediate frames to displayable images in a frontwards direction, a backwards direction, or a combination thereof.

For example, in FIG. 5B, first video clip 504 includes first loop 504 a, second loop 504 b, third loop 504 c, fourth loop 504 d, and fifth loop 504 e. FIGS. 9 and 10 further depict interactive videos 900 and 1000, respectively. In FIGS. 9 and 10, the X axis represents the video clip play time, while the Y axis represents the timeline, or run time, of an interactive video. Each of example interactive videos 900 and 1000 also include a respective first loop 504 a, second loop 504 b, third loop 504 c, fourth loop 504 d, and fifth loop 504 e.

In examples, the first video clip includes live action video. Live action video includes video that was filmed with a camera using real actors and/or objects. In examples, live action video may include no computer-generated graphics or the live action video may include some computer-generated graphics.

In examples, intro video clip 502, first video clip 504, and first exit sequence 506 may have been filmed in one continuous take. In further examples, intro video clip 502, first video clip 504, and first exit sequence 506 may have been filmed separately.

By delivering a live action video clip in a loop while waiting for an input, it may be possible to respond to a user's input more quickly, providing improved transitions between clips. The transitions between the clips may therefore be smooth, creating an improved interactive video experience.

Method 400 continues with step 404. In step 404, upon receiving a first input during delivery of the first video clip, a first exit sequence of the interactive video is delivered, the first exit sequence including a first exit video clip.

The first input may be provided via any of the input devices discussed with reference to first client device 104, second client device 106, third client device 108, first input device 110, second input device, 112, or third input device 114. In examples, the first input may be provided by a user.

The first input may received at any time. For example, FIG. 9 includes example first input 902, which occurs during loop 504 e, and FIG. 10 depicts example first input 1002, which occurs during loop 504 d.

An exit video sequence is one or more video clips that are used to transition interactive video out of the first video loop. For example, FIGS. 9 and 10 depict example exit video sequences 904 and 1004, respectively. The exit video sequence may transition the interactive video into an active phase based on the inputs received.

The exit video sequence 904, 1004 includes a first exit video clip. In examples, the exit clip may include action based on the first input, or the exit clip may include a transition to a video clip including action based on the first input. In the examples of FIGS. 9 and 10, example exit video sequences 904 and 1004 include exit video clip 506.

By providing an exit video sequence, it may be possible to provide a natural transition between an inactive scene and an active scene driven by input. This may make the interactive video appear to be more responsive and engaging to a user. Because the method uses pre-existing video clips, the method may deliver a high-quality interactive video while making efficient use of processor and memory resources. This may allow for the porting of high-quality interactive video onto platforms where similar quality interactive video products were not previously accessible, for example on smart phones and tablets.

In examples, method 400 may include further steps. For example, method 400 may include step 408. In step 408, an intro video clip is displayed before the first video clip. In examples, the intro video clip may include a previous input-driven action including one or more characters or elements of interest. In further examples, an intro video clip may transition an interactive video from a previous action scene into the activity of the first video clip. For example, in an intro video clip a character may sit down in a chair, and in the subsequent first video clip, the character may breathe while sitting in the chair.

In examples, step 402 may include further steps. For example, step 402 may include any of the steps of method 600 of FIG. 6.

For example, step 402 may include step 602. In step 602, first video clip 504 is delivered in a first direction. For example, first video clip 504 may be looped from the start-to-end or end-to-start.

In examples, step 402 may include step 604 of method 600. In step 604, the first video clip may alternate delivery of the first video clip in the first direction and delivery of the first video clip in a second direction.

For example, in FIG. 9 first video clip 504 is delivered in five segments: 504 a, 504 b, 504 c, 504 d, and 504 e. Segments 504 a, 504 c, and 504 e are delivered in a first direction, which in the example is start-to-end of the first video clip, and segments 504 b and 504 d are delivered in a second direction, a reverse direction, or end-to-start of the video clip. The example of FIG. 9 is not intended to be limiting, however. As those of skill in the art will readily understand, in further examples, the first direction may be end-to-start and the second direction may be start-to-end.

By alternating delivering of the first video clip between a first direction and a second direction, it may be possible to provide a natural-looking loop of interactive video using only a short clip of video until a further input is provided. For example, if the video loop includes footage of an actor taking in a deep breath of air in a first direction, reversing the video clip in a loop will create the appearance of the actor exhaling.

In examples, step 402 may include step 606 of method 600. In step 606, the first video clip is delivered at a first playback rate and the first video clip is delivered at a second playback rate. The first playback rate is different from the second playback rate. For example, a video clip may be delivered at a playback rate that is slower than, faster than, a default playback rate. In examples, the default playback rate may emulate the timing at which the events filmed unfolded while they were being filmed.

By varying the delivery playback rate of a video clip, it may be possible to provide more natural-looking interactive video that doesn't appear to be repeating.

In examples, step 402 may further include step 608 of method 600. In step 608, the first video clip may be delivered at least at one additional playback rate. The at least one additional playback rate is different from the first and second playback rates.

In examples, step 402 may further include step 610 of method 600. In step 610, cross fading may be applied between a first frame adjacent to a second frame. The cross fading may be applied by delivering a video clip that includes fading the first frame while allowing the second frame to slowly appear. This may help, for example, to smooth the transition between the first video clip and the exit clip.

In examples, step 402 may further include step 612 of method 600. In step 612, an end point frame of the first video clip is delivered only once during a transition between the first direction and the second direction. An end point frame is a first or a last frame of a loop 504.

For example, FIG. 5B depicts example end point frame 508, which is positioned between first loop 504 a and second loop 504 b. End point frame 508 is the last frame included in first loop 504 a and the first frame included in second loop 504 b. By playing the end point frame 508 only once during the transition between the first and second directions, it may be possible to the appearance of a pause in action, and to thereby make the interactive video appear more natural to a viewer.

In examples, step 404 may include further steps to deliver the exit video sequence upon receiving the first input. For example, step 404 may include one or more of the steps of method 800 of FIG. 8. Method 800 includes step 802. In step 802, at least a portion of a remainder of the first video clip is delivered in the first direction or the second direction.

The remainder of the first video clip starts at the clip playtime when the first input is received. For example, FIGS. 9 and 10 represent example inputs 902 and 1002, respectively. Remainders 906 or 1006 are inclusive of the frames of the video clip between the clip playtime marked by input 902 or 1002 and the end of the loop being played 908 or 1008, in the direction of play. For example, remainder 906 includes loop 504 e between input 902 and an end point frame 908. Remainder 1006 includes loop 504 d between input 1002 and an end point frame 1008.

By delivering at least a portion of the remainder of the first clip, it may be possible to provide for a natural transition between the video clip loops 504 and the exit clip 506.

In examples, step 404 may include step 804 of method 800. In step 804, a remainder of the first video clip is delivered in the first direction or the second direction. Step 404 is similar to step 402, except that in step 404 the entire remainder of the first video clip is delivered.

In examples, step 404 may further include step 806 of method 800. In step 806, a remainder of the first video clip is delivered in the second direction and the first video clip is delivered in the first direction. For example, FIG. 10 depicts that input 1002 is received during loop 504 d, when the video clip is delivered in a second direction. Delivering exit sequence 1004 includes delivering the remainder of the first video clip 1006, and the first video clip in the first direction, or loop 504 e.

By delivering both the remainder of the first video clip in a second direction and the video clip in the first direction during exit sequence 1004, it may be possible to end first video clip at a desired transitional frame before delivering exit clip 506. This may provide a smooth transition between the video clip and the exit clip.

In examples, step 404 may further include step 808 of method 800. In step 808, a remainder of the first video clip is delivered in the first direction or the second direction at an increased playback rate over a default playback rate. For example, remainder 906 or 1006 may be delivered with a higher playback speed over a default playback rate to decrease the delay between the input and when the interactive video appears to react to the input.

In examples, step 404 may further include step 810 of method 800. In step 810, the first exit video clip is selected based on a video clip playtime. The video clip playtime is the amount of time that a video clip has played after playing the start frame of the video clip.

By selecting the first exit video clip based on the video clip playtime, it may be possible to match the action in the selected exit clip to the action at different playtimes of the video clip, allowing for the interactive video to appear responsive sooner than waiting until the end of the video clip. This may provide for more natural-appearing transitions.

In examples, step 404 may include step 812 of method 800. In step 812, the first exit video clip is selected based on an exit clip duration. The exit clip duration is the total amount of time that it takes to deliver an exit clip using a default playback speed.

Selecting the first exit video clip based on the video clip playtime may, for example, allow the interactive video to deliver an exit clip having a shortened duration when the video clip duration is relatively long. This may ensure that an exit sequence does not take longer than a maximum duration to deliver.

In examples, step 404 may include step 816 of method 800. In step 816, the first exit video clip is selected based on an exit clip content. This may allow the first exit video clip to be selected based on the action associated with the input received. For example, if a user provides an input to move a character to the left, the first exit video clip may first move the character's head to face the direction he will walk in. If a user provides an input for a user to open a door, however, the first exit video clip may extend the user's arm towards the door.

In examples, step 404 may include steps 818 and 820 of method 800. In step 818, a second video clip is delivered in a second loop. In examples, the first video clip may be delivered in a first area of a display and the second video clip may be displayed in a second area of a display. In examples, the first video clip and the second video clip may respond to the same inputs or different inputs.

For example, FIG. 11 depicts display 1100. Display 1100 includes a first area 1102 where a first video clip is delivered, and a second area 1104 where a second video clip is delivered. In the example, of display 1100, the first video clip includes a video of a rocket, and the second video clip includes a video of an astronaut.

By allowing multiple video loops to be present on a single display, it may be possible to provide an efficient high-quality, interactive video with multiple interactive features.

In step 820, upon receiving a second input during delivery of the second video clip, a second exit video sequence is delivered including a second exit clip.

In examples, a first set of inputs may be correlated to actions of the rocket in the first video clip, and a second set of inputs may be correlated to the actions of the astronaut in the second video clip. In examples, a further set of inputs may be correlated to both the rocket and the astronaut.

In examples, a first video clip may correspond to inputs received from a first user and the second video clip may correspond to inputs received from a second user in a single interactive video. For example, separate players may be playing the same instance of a video game.

The methods describe above may allow for the creation of responsive interactive video experiences using previously created video clips, while avoiding the additional cost and complexity of creating custom computer-generated graphics. The methods may further create an interactive experience that is more realistic and relatable to users because real actors and objects are used.

The methods described above may also allow for the delivery of high-quality, responsive, realistic interactive video that can be displayed or deployed on devices with less capable graphics processing units and limited batter life than standard desktop computers. This may make interactive video content more accessible to users.

In examples, delivering the first video clip and the first exit sequence may comprise displaying the first video clip and the first exit sequence on a display. For example, the first video clip and the first exit sequence may be displayed on any display 208, including a display integrated onto first, second, or third client devices 104, 106, or 108.

Alternatively, the first video clip and the first exit sequence may be displayed on an external display connected to a client device, such as display 116. For example, FIG. 12 depicts sequence diagram 1200. As may be seen in sequence diagram 1200, first client application 304 may send first message 1202 to second client application 306. Second client application 306 may respond by sending second message 1204 to display 116 in turn.

In examples, first message 1202 may include input received at first client application 304. In further examples, first message 1202 may include video clips or frames.

In examples, second message 1204 may include instructions to display one or more video clips. In further examples, second message 1204 may include actual video clips or frames to be displayed on first client application 304.

The system depicted in sequence diagram 1200 may allow a user providing inputs for an interactive video on first client device 104, for example a smartphone, to stream the interactive video to a second client device 106, for example a game controller, which can display the interactive video on a separate display 116, for example a television. This may allow one or more users to view the interactive video on a larger screen. It may also allow one or more additional users to interact with the interactive video.

The system depicted in sequence diagram 1300 may allow a user to provide inputs to a client device that are sent to a server, and to receive interactive video from a server in turn based on the inputs.

For example, sequence diagram 1300 depicts first client application 304 transmitting a first message 1302 to server application 302. In examples, first message 1302 may include inputs. Server application 302 transmits third message 1306 back to first client application. In examples, the third message may include, for example, one or more video clips or one or more video frames in response to the input provided in the first message. For example, third message 1306 may include the first video clip and the first exit sequence.

In examples, sequence diagram 1300 may further include a third client application 308. As may be seen in FIG. 13, third client application 308 may further transmit a second message 1304 to server application 302. Second message 1304 may include further inputs from an additional user. In response, sever application 302 may transmit third message 1306 to third client application 308 in addition to first client application 304. The system depicted in FIG. 13 may allow multiple users to interact with the same interactive video.

FIG. 14 depicts method 1400, an example embodiment that may be used to create an interactive video. Method 1400 begins with step 1402. In step 1402, instructions are provided to deliver a first video clip of the interactive video in a first loop.

Providing instructions may include creating a script, source code, object code, or executable code to perform actions. In examples, the instructions may be created to run on a server device, a client device, or a combination thereof, as described above.

For example, step 1402 may provide the following example implementation of an interactive video. The example is provided in pseudo code, with comments noted by “//”:

// load the first video clip to loop queuebg(“first_video_clip.mov”) // wait for prior clip to finish wait(“prior_video_clip_done”) // start playing first video clip in loop playqueuedbg( )

Method 1400 continues with step 1404. In step 1404, instructions are provided to wait for input during delivery of the first video clip.

For example, step 1402 may provide the following example pseudocode:

-   -   wait(“input”)

Method 1400 continues with step 1406. I step 1406, instructions are provided to deliver a first exit sequence of the interactive video, the first exit sequence including a first exit video clip.

For example, step 1406 may provide may provide the following example pseudocode:

// progress corresponds to playtime over first video clip length  progress = playtimeInCurrentClip( ) / currentClipLength( ) // determine quadrant of first video clip playtime (progress) // select and queue exit video clip // calculate when to exit first video clip to the exit clip if (progress < 0.25) then queuebg(“exit clip A.mov”) frame = math.floor(remainingPlaytime( ) * 0.25) − 1 elseif (progress < 0.5) then queuebg(“exit clip B.mov”) frame = math.floor(remainingPlaytime ( ) * 0.5) − 1 elseif (progress < 0.75) then queuebg(“exit clip C.mov”) frame = math.floor(remainingPlaytime ( ) * 0.75) − 1 else queuebg(“exit clip D.mov”) frame = math.floor(remainingPlaytime ( ) * 0.75) − 1 end // deliver at least a portion of a remainder of the first video clip waitForFrame(frame) // play the exit clip playqueuedbg( )

In examples, method 1400 may further include steps to provide instructions to provide the features described in methods 400, 600, and 800.
